Eosinophils are cells, the phagocytizing complexes of Ar-AT, represented mainly by IgE. After maturation in the bone marrow, eosinophils for several hours (about 3-4) are in circulating blood, and then migrate to tissues where their life span is 8-12 days. For eosinophils, the daily rhythm of fluctuations in the blood is characteristic, the highest indices are recorded at night, the lowest ones are observed in the daytime. The action of eosinophils manifests itself in sensitized tissues. They are involved in hypersensitivity reactions of immediate and delayed type.
